15th Annual Tour of the S.F. Hills

Sunday, November 4th

Meet at the parking lot across the street from the Marina Safeway at 9
A.M.

The ride explores a multitude of neighborhoods in the city, taking the
most difficult path from cafe to taqueria. With the many hilltops in
the city, and with the usual good luck with weather conditions, the
riders are treated to frequent magnificent views. The parade of
cyclists winding down Lombard St. and then climbing the 32% grade on
Filbert St. always attracts the attention of tourists. Other sites
explored on the ride are Potrero Hill (with the fast descent down the
"other" crookedest street in the world), Coit Tower, Nob Hill, and Mt.
Davidson. A bonus feature is the optional ascent of the Broderick St.
sidewalk in Pacific Heights. This street, below the Levi mansion, is so
steep that it is blocked off to traffic - the upper half being a
driveway more crooked than Lombard St. A casual pace on the ride
ensures that the attrition rate is low, but the prospect of climbing
Hill St. after scarfing burritos in the Mission always sheds a few
riders.
